The REXS2025 Conference has considered two awards among participants.
REXS2025 Best poster (early career) Prize sponsored by the Spanish Synchrotron Radiation User Association (AUSE)
The best poster prize recognizes an outstanding high-quality scientific contribution using or developing Resonant Elastic X-Ray Scattering approaches by an early career participant with a poster presentation at REXS 2025 conference.
The prize jury were composed by two of the chairs of the Local Organizing and International Committees -Dr. Gloria Subías and Dr. Sonia Francoual. The REXS2025 poster prize was awarded to Hyein Jung -PhD student at the Institute for Optics and Atomic Physics, Technical University Berlin and Department of Physical Chemistry, Fritz Haber Institute of the Max Planck Society, Berlin, Germany- for her poster “Controlling Spin Periodicity in a Helical Heisenberg Antiferromagnet” in which she presented the results of resonant X-ray diffraction experiments aimed at probing the effects of femtosecond laser excitation on the spin interactions in 4f antiferromagnets.

REXS2025 Career distinction award
The REXS2025 Career Distinction Award recognizes a career long outstanding contribution to the field of Resonant Elastic X-ray Scattering of one of the REXS conference participants. The awarded person will have various relevant achievements in either developing REXS techniques (at the level of methodologies, instrumentation, theoretical understanding) or having done relevant scientific discoveries using REXS techniques, or both.
The REXS2025 Career Distinction Awards has been awarded to Prof. Gerrit van der Laan from the Diamond Light Source "for lifelong contributions in the field of X-ray resonant scattering”. Prof. van der Laan has made a pathbreaking contribution in the field of x-ray spectroscopy and scattering. Non exhaustiverly, he is one of the pioneers on the use of resonant magnetic scattering in nanostructures1, co-discovered the sensitivity of REXS to chiral magnetic domains2 and more recently the related CD-REXS extinction rule for the investigation of fundamental properties of Skyrmion lattices and their 3D structure3,4; he has co-lead also contributions to instrumentation and theoretical understanding, such as the introduction of FMR approaches in REXS5 or proposing a possible mechanism for REXS sensitivity to chiral electric-polar domains6. Furthermore, has contributed with relevant reviews on the field, favoring the use of REXS Fourier description and providing visionary thoughts on the use of coherence1, presently at the heart of the upgrade to 4thgeneration light sources.
The award was strongly supported by the members of the REXS2025 International Committee, at proposal by the chairs of the International and Local Organizing Committees.
